Features

  • Search YouTube videos without using the official API
  • Retrieve video transcripts
  • Store video information and transcripts in a vector database
  • Perform semantic search over stored video transcripts

Prerequisites

  • Python 3.8+
  • Google API key for embeddings
  • uv package manager

Installation

  1. Clone this repository

  2. Create and activate a virtual environment using uv:

uv venv
# On Windows:
.venv\Scripts\activate
# On Unix/MacOS:
source .venv/bin/activate
  1. Install dependencies using uv:
uv pip install -r requirements.txt
  1. Create a .env file with your Google API key:
GOOGLE_API_KEY=your_api_key_here

Running the Server

There are two ways to run the MCP server:

1. Direct Method

To start the MCP server directly:

uv run python server.py

2. Configure for Claude.app

Add to your Claude settings without using any package manager this works for windows:

"mcpServers": {
  "youtube": {
    "command": "C:\\Path\\To\\Your\\Project\\.venv\\Scripts\\python.exe",
    "args": ["C:\\Path\\To\\Your\\Project\\server.py"],
    "env": {
      "GOOGLE_API_KEY": "your_api_key_here"
    }
  }
}

Using Uv package manager this works for windows:

"mcpServers": {
  "youtube": {
    "command": "uv",
    "args": ["--directory", "C:\\Path\\To\\Your\\Project", "run", "server.py"],
    "env": {
      "GOOGLE_API_KEY": "your_api_key_here"
    }
  }
}

This server can be used with any MCP-compatible client, such as Claude Desktop App. The tools will be automatically discovered and made available to the client.

Example Usage

  1. Start the server using one of the methods described above
  2. Open Claude Desktop App
  3. Look for the hammer icon to verify that the YouTube tools are available
  4. You can now use commands like:
    • "Search for Python tutorial videos"
    • "Get the transcript of this video: [video_url]"
    • "Search through stored video transcripts about machine learning"

Debugging
